INHALAlION DEVICE Filed Dec. 27, 1932 7., www/74%@ Patented Dec. 24, 1935 PATENT OFFICE I' INHALATION DEVICE n Henri Adolphe Gilquin, Ain-Seba, near Casablanca, Morocco Application December 27, 1932Serial No. 649,054 In Morocco January 27, 1932 3 Claims.

The object of the present invention is to permit, in a simple and rational manner, of the inhalation of pure air, either natural or treated, for instance ldried or super-oxygenated or mixed 5 with medicinal or other products.

To this effect, in accordance with the invention, the air intended for inhalation is supplied to a container and is forced to diffuse slowly and regularly through a partition, permeable to air over the whole or part of its surface, on which v rests the head of the person (or persons) undergoing treatment, by preference in the recumbent position, the other walls of the said container being impermeable to air.

The device forming the subject of the invention is composed, in principle, of a pillow, cushion or other article, only the upper wall of which, intended to support the head of the person (or persons) undergoing treatment, is permeable to air,

either over the whole of its surface or in certain zones only. The air, the admission of which to the interior of the device is effected through one of the non-permeable faces, is slowly and regularly diffused through the permeable wall on which the head of the person rests and surrounds the said head with a zone of pure air constantly renewed, the vivifying effect of which is particularly effective and benignant.

In comparison with installations by which it is y sought to obtain the general treatment of the Whole of the atmosphere of a room at the same time, the invention represents an important progress. In point of fact, in the case of the said installations, the large volumes of air to be treated and put into circulation entail heavy expense; moreover, it is very diflicult to manage to homogenize the air of a room perfectly, in view of the fact that dead zones are produced there; finally it is impossible to adapt the treatment and the supply of the air to the particular requirements of each person. These drawbacks are eliminated by the device in accordance with the invention, which device relieves, moreover, immediately and completely, the person of his expirations and presents a possibility of regulating the supply of air at will.

One form of constructing the device is shown diagrammatically, by way of example by no 50 means limitative, in the annexed drawing, to

which reference will be made in the following description.

Fig. 1 is a view in vertical longitudinal section of an example of installation comprising the ap- 55 plication of the device.

(Cl. 12S-185) Fig. 2 is a ground plan of a form of construction of the device.

Fig. 3 is a view in vertical section following A-A on Fig. 2 and Fig. 4 a view in vertical section following B-B 5 on Fig. 2.

In the drawing, I is a container composed, for instance, of a cushion or pillow, 2 the springs, on the upper wall Ia of which will rest the head of the person (or persons) who is to inhale and 10 which, by preference, is extended, it being possible and advantageous to carry out the treatment during sleep.

The upper wall I a is permeable to air and to this end it may be composed, for instance, of a l5 metallic net covered with a permeable cloth.

The other walls, such as I b, Ic, Id, are, on the other hand, impermeable to air being, for such purpose, of wood or of a close fabric.

The air, aspired by a fan 3, traverses, as re- 20 quired, one or more purifying and treating devices 4 and is forced into the interior of the container I, a regulating device 5 being provided in order to permit ,of varying and regulating the volume of air admitted. 25

The regulation of the supply of air may be effectedvat will by regulating the speed of the fan 3 by means of a device causing the power at the terminals of its driving motor to be varied.

The wall I a may be permeable over the whole 30 of its surface or have certain permeable zones only, by preference for the portion of the head in the region of the nose.

In the form of construction represented by Figs. 2 to 4, the head support, carried out in the 35 form of a pillow, is composed of a frame I0, of wood or metal, constituting an inside fitting entirely surrounded by an envelope I6 of a fabric such as closely woven and thick cloth, practically impermeable to air.

The upper surface of the pillow is provided with two orifices II and I2, cut from a spot where they will be located practically adjacent to the nose when the head of a person in a re 45 cumbent position rests on the pillow, and fitted with a fine metallic cloth I3, or equivalent, this cloth regulating the diffusion of the air.

A loose cover I4 of washable meshed fabric, of the kind, for instance, known under the name of Cellular fabric, fixed at the sides, for instance, by press studs I5, covers the upper part and contributes, by reason of its construction, in regulatng the diffusion of the air.

It is understood that itis possible, without departing from the scope of the invention, to conceive variants and improvements in details.

I claim: Y

1. A head supporting device constituting a pillow and comprising an open framework, an envelope formed of material substantially impervious to the passage of air and enclosing said framework, said envelope having a top head supporting portion provided with an opening on each side of the longitudinal axis thereof, foraminous metallic members arranged in said openings and permitting the passage of air therethrough, and means for supplying air to the interior of the envelope.

2. A head supporting device as claimed in claim 1, characterized in that said envelope forms an internal chamber containing air, and

spring means resiliently sustaining the head sup'- porting portion of the envelope.

3. A head supporting device constituting a pillow and comprising an open framework, an envelope including said framework and formed of material substantially impervious to the passage of air, said envelope having a top head supporting portion provided with openings, one opening being arranged at each side of the center of the envelope top, a foraminous metal member arranged in each opening and controlling the passage of air therethrough, and an air supply pipe connected to the interior of said envelope and having a cross sectional area substantially less than each of said openings.
